Time Travel: A Reality in Mesoscopic Physics

This book is aimed at postgraduate and Ph.D. students specializing in condensed matter physics, quantum mechanics, and the theory of relativity. It explores fundamental problems in physics that can be addressed in the mesoscopic regime. Some of the key topics covered include:

a) The state of a tunneling particle under a barrier

b) A local description of the state of a quantum particle

c) Reality of time travel leading to reconciliation of the classical and quantum laws

The book also sets the stage for developing an alternative description of quantum mechanics and how scattering phase shift can be used to probe local density of states. It highlights essential differences from traditional statistical mechanics and discusses the potential applications and future technologies stemming from breakthroughs in basic science, which will be of interest to researchers.

Prof. Prosenjit Singha Deo has worked at the S.N Bose National Centre for Basic Sciences in Kolkata, India, since 1999. He has successfully guided several Ph.D. students leading to their Ph.D. in physics and also mentored a few postdocs. His works are mostly analytical and theoretical, but he has collaborated closely with experimentalists and co-authored many scienti?c papers with experimentalists. He has consistently worked on the problems elaborated in the book for over 25 years and more. He has also taught several courses in physics at the M.Sc. level. Before joining S. N. Bose Centre, he spent about 3 years in Europe as a postdoctoral fellow. He did his Ph.D. in physics in 1996 from the Institute of Physics, Bhubaneswar, India.

Kanchan Meena joined S.N. Bose Centre, Kolkata as a PhD student under the supervision of Prof. P. Singha Deo in 2019. She submitted her thesis in 2024 and a large part of her PhD work has fueled this book. She has played a proactive role in her research endeavor and she is greatly interested in a career in Physics research. She did her masters in Physics from Vardhaman Mahaveer Open University, Rajasthan, India. Her hobbies include watching classic movies, photography and dancing. She is also interested in popularizing physics among friends and young souls. She has suffered the brunt of the pandemic and fought it bravely to tell the tale and now she wants to move forward.
